Abstract
This letter proposes a fast handoff protocol (FHP) for cellular IEEE 802.11e wireless local area network (WLAN) systems. The FHP, which is standard compatible, provides a controlled contention period (CCP) designated for handoff requests (HO-REQs), arranges these HO-REQs to contend sequentially in CCP, and proposes a fuzzy adjustment method (FAM) to determine a proper length for CCP. Simulation results reveal that the FHP can significantly decrease the forced termination rate of HO-REQs and still enhance the system throughput of contention period for cellular IEEE 802.11e WLAN systems
